if u want to post more than one pic, just place the images inline with the message using bbcode tags or just press the insert image button. as for screenshot programs, i just use the method described by betauser2. and if you only want to grab the topmost window, press alt and then print screen.

Ehmm, well, compared to printscreen, with a good screenshot program you can save time with features like automatic edges detection (window capture, etc), autoscroll, capture of every types of popups menus, text/arrows, choice of picture quality, size, etc, on the fly, before to save your picture.

With printscreen you've to edit the pic with a graphic program once the screenshot is saved. That's the main difference .

...plus with Faststone, the one I'm using, you get theses funny peeping eyes moving in your taskbar when the program is loaded , I really like it... lol

Ok I'm joking about this one, but I've noticed they did change the taskbar icon in version 2 for a very serious one... I'll mail them to tell I prefer the former icon ...
